Composting in Boston
Composting is the controlled decomposition of organic material. You create a rich, black soil that is great for your yard and garden. By composting, you reduce your garbage, save money, and enrich the soil.

City of Boston Compost Site
The City of Boston compost site is where we process all yard waste. We turn it into compost and leaf mulch, which is used in many community gardens and parks across the City.
What makes a good compost pile?
The elements of a good compost pile include biodegradables, organic material, air, and moisture. For the best results, follow these compost instructions. The Massachusetts Department of Environmental Protection also has information on composting.
To build your compost, you will need nitrogen-rich “green” materials, like:
- food scraps (but not meat, dairy, fats, and oils)
- fresh grass clippings
- weeds (not laden with seeds), and
- coffee grounds.
You will also need carbon-rich “brown” materials, like:
- dried leaves
- shredded paper, and
- pine Needles (pine needles should not make up more than 10 percent of the material in the pile).
Leaf and yard waste
From April until the first week of December, the City collects and composts residents’ yard waste on specific recycling days.
- Please place leaves and yard debris in large paper leaf bags or in barrels labeled “Yard Waste.” We won’t take plastic bags. Tie up branches with string and place them in barrels.
- Please don’t include branches that are longer than three feet. You can get a “Yard Waste” sticker for your barrel. Call 311 or make a request online. You can only get two stickers per household.
